Demine spelled 18 out of 24 words correctly on a test. What percent of the words did Damien spell correctly

A. 24
B.75
C.18
D.65

Answer:

35%

A percentage is a way of representing how much of a whole is present. Like a decimal or a fraction, a percentage is another form of showing these ratios and portions.

From the chart, we need to find how the total number of female students and the total number of male students.

Female

[tex]18+12=30[/tex]

Male

[tex]5+15=20[/tex]

First, take the number of female students that prefer pizza and divide it by the total number of female students.

[tex]\displaystyle \frac{18}{30}[/tex]

[tex]\displaystyle \frac{3}{5}[/tex]

Convert the fraction into a decimal by using a calculator.

[tex]\displaystyle \frac{3}{5} = 0.6[/tex]

Then, convert the decimal to a percentage by multiplying by 100.

[tex]0.6\times100=60\%[/tex]

The percentage of female students who preferred pizza is 60%.

Take the number of male students that prefer pizza and divide it by the total number of male students.

[tex]\displaystyle \frac{5}{20}[/tex]

[tex]\displaystyle \frac{1}{4}[/tex]

Convert the fraction into a decimal by using a calculator.

[tex]\displaystyle \frac{1}{4}=0.25[/tex]

Then, convert the decimal into a percentage by multiplying by 100.

[tex]0.25\times100=25\%[/tex]

The percentage of male students who preferred pizza is 25%.

Finally, subtract the percentage of male students who preferred pizza from the percentage of female students who preferred pizza.

[tex]60\%-25\%=35\%[/tex]

The final answer is 35%.

Answer:

A) . f(x) = –16x2 + 99x + 6  

AAAAAAA is the answerrrrrr!!!!

Step-by-step explanation:

By analyzing the data and the situation modeled, we got the vertex of the quadratic function, and with that, we conclude that the correct option is:

f(x) = –16x^2 + 99x + 6

Here we have the table:

x         y

0        5

1         90

2        140

3         160

4         150

First, we know that this represents the height of a ball that is thrown in the air, and we know that it must go up and then back, this means that the leading coefficient must be negative.

So there are two options:

f(x) = –16x^2 + 99x + 6

f(x) = –36x^2 + 37x + 5

Analyzing the data, we can see that the maximum value is at x = 3, so we can assume that the vertex is near x = 3.

Remember that for a quadratic:

y = a*x^2 + b*x + c

The x-value of the vertex is at:

x = -b/2a

Then for our functions the x-values of the vertex are:

f(x) = –16x^2 + 99x + 6

x = -99/(2*-16) = 3.1

f(x) = –36x^2 + 37x + 5

x = -37/(2*-36) = 0.5

The option that has a vertex near x = 3 is the first one, so that is the best fit.

f(x) = –16x^2 + 99x + 6

I am pretty sure it is D because the numbers on the chart don't seem inconsistent. You go from 11 to 2 which would give a big drop so it wouldn't be a linear function.

Answer:

A. –x – 6y = 42

Step-by-step explanation:

Multiply everything by 6:  

6y = x + 42

The answer you are looking for is -6y+x=-42

We start by multiplying everything by 6

·6y=X+42

We then need to move X to the other side of the equation so we subtract X rom both sides.

·6Y-X=42

In order to solve the question X must be positive so we multiply everything by a quanitity of -1

·-6y+x=-42

Now this is in stardard form, so in conclusion your answer is -6y +x = -42

-I hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.

Answer: 6700 meters

Step-by-step explanation:

From the question given, we are informed that Gephart is traveling from his house to the history museum and that the distance from home to the history museum is six and seven-tenths kilometers.

In order to know the distance in meters

that he will travel to the museum, we have to multiply the convert the distance given in kilometers to meters. This will be:

1000 meters = 1 kilometer

Therefore, 6 7/10km = (6 7/10 × 1000m)

= 6 7/10 × 1000

= 67/10 × 1000

= 67 × 100

= 6700 meters

He'll travel 6700 meters to the museum.
